EnumToString

A string with a text representation of the enumeration. To get the error message call the GetLastError() function.

Note

The function can set the following error values in the _LastError variable:

ERR_INTERNAL_ERROR – error of the execution environment

ERR_NOT_ENOUGH_MEMORY – not enough memory to complete the operation

ERR_INVALID_PARAMETER – can't allow the name of the enumeration value

Example:

enum interval // enumeration of named constants { month=1, // one-month interval two_months, // two months quarter, // three months - a quarter halfyear=6, // half a year year=12, // a year - 12 months };//+------------------------------------------------------------------+//| Script program start function |//+------------------------------------------------------------------+voidOnStart() {//--- set the time interval equal to one month interval period=month;Print(EnumToString(period)+"="+IntegerToString(period));//--- set the time interval equal to a quarter (three months)period=quarter;Print(EnumToString(period)+"="+IntegerToString(period));//--- set the time interval equal to one year (12 months)period=year;Print(EnumToString(period)+"="+IntegerToString(period));//--- check how the order type is shownENUM_ORDER_TYPE type=ORDER_TYPE_BUY;Print(EnumToString(type)+"="+IntegerToString(type));//--- check how incorrect values are shown type=WRONG_VALUE;Print(EnumToString(type)+"="+IntegerToString(type));// Result:// month=1// quarter=3// year=12// ORDER_TYPE_BUY=0// ENUM_ORDER_TYPE::-1=-1 }
